Application filed December 10, 1921.

To all whom it may concern Be it known that I, 'NOAH WALKER, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in I Reversible Agitating Apparatus for Fluids,

of which the following is a specification.

One object of my present invention is to provide improved apparatus ofsimple and durable construction which will be operative to efiect theflow or movement of liquid in a container and in which the apparatus iscapable of changing the direction of said movement of the liquid.

Another object is to make my improved apparatus of such constructionthat it will include two similarly operative propelling devicespositioned relatively close together and actuated from a common sourceto effect said movement of the liquid.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is a front elevation of myimproved apparatus showing the same positioned relatively to acontainer; a portion of the container being illustrated in section,

Figure 2 is a view of said apparatus looking in an opposite directionfrom that in which the device is illustrated in Figure 1, and

Figure 3 is a side view looking in the di rection of the arrow at inFigure 1.

Referring to the drawings, I have illustrated my invention in connectionwith a container 12 having a horizontal partition or board 13. Thiscontainer may be of any desired construction for holding liquid up to alevel above the board; it being one of the objects of my invention toprovide the apparatus for any purpose or condition to eflect the flow ofliquid in an alternating manner upward and downward through the holes 14and 14 in the board .13.

Referring specifically to the apparatus of my invention, 15 representsan actuating head including a base 16 which may be made of cast metaland adapted to set upon the top of the container 12, as clearly shown inFigure 1. A standard 17 has a flanged bottom 18 which is boltedto thebase.

The standard 17 has a recess 22 which dep n m t t p surface and he pp rSerial No. 521,557.

sides of the recess are provided with bearing caps 25 and serve asbearings for a horizontally disposed transverse shaft 26; said shaftextending across the recess 22 and projecting beyond the'outer ends ofthe bearing portions 23 and 24 and caps 25. The standard 17 has opposedlateral projections 27 and 28 which at their outer ends provide bearingsfor two propeller shafts 29 and 30; said propeller shafts extendingthrough holes in the base 16. Said projecting ends of the transverseshaft 26 have bevel gears 31 and 32 respectively secured thereto andwhich meshwith bevel gears 33 and 34 which are secured on the upper ends.of the propeller shafts 29 and 30 respectively atpositions above thelateral bearings 27 and 28.

The shaft 26 has a gear wheel 35 secured thereon; said gear wheel beingpositioned so that a portion of itextends into the recess 22. Theopposite ends of the hub of the gear wheel 35 are adapted to abut theouter opposed end surfaces of the bearing portions 23 and 24 and bearingcaps 25.

The propeller shafts 29 and 30 have blade propellers secured thereto;said propellers being located within the respective holes 14 and 14 ofthe board 13; the blades of said propellers being pitched at oppositeangles so that when the propeller shafts rotate in unison in oppositedirections they will serve to both move the liquid in the same directionthrough the holes 14 and 14*.

I mount upon thebase 16 power driven reversing means 36 of a suitablecharacter. In the form of my invention illustrated said power drivenreversing means includes a wheel 43 which can be rotated in eitherdirection by the action of said reversing means. The wheel 43 drives thewheel 35 and thus the wheel 35 can be rotated in either direction andthe propeller shafts and propellers can be rotated in either direction.

By the structure above set forth the liquid can be moved through theholes 14 and 14 first in one direction andthen in an opposite direction,

Reference is hereby made to my applicav 1,498,217 rarest c rries.

parts of the portions 23 and 24at opposite tion for U. S; Patent filedMarch 13th, 1924,

tion may be changed without departing from 111ySGlf to the preciseconstruction set forth,

but consider that I am at liberty to make such changes and alterationsas fairly come Within the scope of the appended claim. 7

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is In apparatus of the character described, acentral supporting 'structure including upright portions spaced apartproviding bearings; a transverse shaft mounted in said bearings; adriving Wheel mounted on said shaft and extending into the space betweensaid upright portions; gear Wheels on said transverse shaft at positionsoutside of said upright portions; upright propeller shafts;

bearings at opposite sides of; said first supporting structure, saidpropeller shaftsbeing mounted in said latter bearings; gear Wheels onsaid propeller shafts meshing With the gear wheels on said first shaft;a base upon which said central supporting structure is mounted: andpower driven reversing means on said base for rotating said transverseshaft and operative upon said first wheel in the direction of a planepassing between said upright portions.

In. Witness whereof I have signediny name to this specification in thepresence of two subscribing Witnesses. I
